ENGINE-REGISTER.

' SPECIFICATION forming part of Letters Patent No. 297,670, dated Apri129, 188%.

Application filed April 13, 1881. (N0 model.)

To (ZZZ whom it may concern.-

Be it known that I, CYRUS CHAMBERS, J r., of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Engine- Registers; and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

. Figure l is a longitudinal vertical section of the machine on line y y of Fig. 2. Fig. 2 is a transverse vertical section. on line 00 a: of Fig. 1. Fig. 3 is a section of the lower one of two adjacent wheels on aplane at right angles to its axis, and a top view of the interlocking wheel, showing the mode in which the adjacent wheels are united and driven. Fig. 4 is a side elevation of one of the numbered wheels, showing its hub, rims, notches, tooth, and pin.

The sameletter indicates the same part whenever it occurs in the drawings.

The object of this invention is to improve the method of supporting and turning the dialwheels of an engineregister; to enable an alarm to be sounded on the bell at any de sired number within the limits of the counting capacity of the machine, and said number varied at pleasure to facilitate the setting of the dial-wheels and their retention in proper interlocked position; to engage and disengage the driving mechanism at any moment when required, and thus to produce a compact, convenient,economical,and positively-acting register, applicable to the general purposes of such an instrument.

My improvements consist in placing a series of interlocked count or dial wheels loosely on inclined studs supported in cast lugs forming part of the bottom of the case; in providing each wheel with a series of ten holes, one opposite each digit on the wheel, for the reception of a removable pin, which canbe set in any hole, opposite any digit, on any wheel, and operate the bell when the number indicated by the selected digit is in position to bring the pin into engagement with the tappet which works the bell-hammer; in combining with the interlocked'wheels a worm-driving mechanism, and in devices for facilitating the adjustment of the wheels and alarnrpin, preventing them from being intentionally or accidentally thrown out of their normal relations, all as hereinafter more particularly set forth.

In the drawin'gs,A marks an oblong, rectangular case, closed at top by a lid, L, perforated in front with a horizontal row of openings, J, through which to read the register, and provided at one end with a bell, F, upon which an alarm is given at the required points in the count, as hereinafter explained. In the back of the case is a journal, G, through which the drivingshaft K enters, upon which is a worm, WV, which engages with the notches of units-wheel D to impart motion to the mechanism. The lid L is attached to the case by hinges b. It supports, on its lower side, the hammershaft E, to which is fixed the bellhammer H, and an arm, a, which is actuated by a spring, S, whose reaction tends to throw hammer H against the bell. The hammer hangs outside the case, the shaft E passing out through a notch in the end of the case.

To shaft E is attached a tappetplate, I, having the form shown, with projections t, which serve as tappets to engage with an actuating-pin, 19, inserted in any one of the dialwheels. On the inside of the lid are also cast a series of lugs, Z, which,when the lid is closed, come into contact with the upper ends of the studs O,on which the dial-wheels are supported and turn. The studs 0 are inserted in lugs B,cast on the inside of the bottom plate of the case.

The dial-wheels D, D, D, D and D are provided with long hub's d and a cylindrical flange, on the face of which the digits are inscribed in a vertical position, the lower edge of said flange being divided into ten equidistant notches, and its upper rim provided with an opening divided by a tooth, t, as shown, for a purpose hereinafter explained. The top ofeach dial-wheel is provided with ten equidistant holes,h, corresponding in position with the digits on the face of the wheels. These holes are for the reception of the pin 2, which can be placed in any one of them at pleasure, and when brought by the rotation of the wheel into contact with one of the tappets I of the tappet-plate I will raise and release said plate and cause an alarm to be sounded on the bell.

The studs 0, on which the wheels turn loosely, are set in an inclined position, so that the figures shall be presented in a horizontal line. The upper flanged rim of each wheel interlocks with two notches on the lower rim of the next wheel on the left, as shown in Fig. 3. The left-hand or driven wheel is held immovable by this interlocking at all times, except when it isnecessary to move to register a change of count, when the opening 0 of the up per rim of the righthand or driving wheel comesinto the position,(shown in Fig. 3,) and permits the tooth of the driven wheel to pass within the rim, and the driving-tooth t to enter a notch of the driven wheel, and move it one-tenth of a revolution.

The mechanism is driven by worm \Y on shaft K, which receives its motion by connection with the engine or other machine whose movements are to be registered. The use of the worm obviates all danger of an inaccurate count, as all the parts are firmly geared and their movements rendered positive and certain.

If preferred, this register can be adapted, by obvious changes, to be driven by a reciprocating driving device like that described in my application Case A) of even date herewith.

The dial-wheels can be lifted off their studs 0 when the lid L is raised, and adjusted as de sired. hen the lid is closed, they are prevented from rising, and their relative position cannot be changed. The lid cannot be closed or the machine operated while any wheel is out of place and not properly interlocked with the adjacent wheels. At the outset of a count the wheels are all set at zero, and the lid closed and locked, if desired, to prevent any accidental or intentional change in the relative positions of the wheels. The wheels are arranged in the usual order, the units-wheel I) being on the right and the ten-thousands wheel D being on the left of the series. The series may be indefinitely extended as required.

Having thus fully described my improve ments in engine-registers, what I claim, and desire to secure by Letters Patent, is

1. In an engine-register, a revoluble shaft provided with tappets and a bell-hainmer arm, said shaft and arm being spring acutuated, as specified, in combination with a series of count or dial wheels, each having a row of ten holes, and a pin adapted to be inserted into any one i of said holes, substantially as described, and for the purposes set forth.

2. In combination with the dial-wheels I) D, &c., the pin 9), tappets t, plate I, shaft E, hammer II, and bell F, all constructed, arranged, and operating substantially as described.

3. In combination with the case A, the lugs B, inclined studs 0, lugs Z, and wheels D D, &c., constructed and operating in the manner and for the purpose specified.

4.. The combination of the alarm mechanism and the lugs Z wit-h the lid L of the ease, in order that when the lid is opened the wheels can be readily removed or adjusted and the alarmpin set, as desired.

5. The combination of the lid L, provided with the lugs Z and the dial-wheels, to prevent the removal or displacement of the wheels when the lid is closed, as set forth.

(5. In an enginercgister, a series of count or dial wheels loosely mounted on diagonal or inclined studs, so that the upper face edge of the first or driving wheel of said series shall lie immediately under the lower edge of the adjoining wheel, said upper face edge of the drivingwheel being provided with a tooth, the said under lower edge of the adjoining or driven wheel being provided with ten notches, whereby at each revolution of the drivingwhcel the driven wheel is turned one-tenth of a revolution, as set forth, and at the same time permitting the wheels to be raised and lowered on their respective studs, to effect the disengagement ofthe teeth and notches aforesaid, for the purpose of adjustment, substantially as described and set forth.

7. In an engine-register, a series of count or dial wheels loosely mounted and inclined, so that the upper face edge of the first or driving-wheel of said series shall be immediately under the lower edge of the adjoining wheel, said upper face of the driving-wheel being provided with a tooth, the said under lower edge of the adjoining or driven wheel being provided with ten notches, whereby at each revolution of the driving-wheel the driven wheel is turned one-tenth of a revolution, as set forth, in combination with a d rive-shaft and worm, said worm engaging with the notches 0n the under side of one of the dial-wheels, substantially as specified.

In testimony that I claim the foregoing as my own invention I affix my signature in presence of two witnesses.
